VENTI LAT'OR FOR REFRIGERATOR-CARS.

SPECIFICATION forming part of Letters Patent No. 646,628, dated April 3, 1900. 3

' Application filed September 13, 1 897. Serial. NIL-6511.497. (No model.)

To a whom i m y 007M612: this sliding feature may be omitted and the Beitknown that I, ALEXANDER RICHMOND, coaming immovably hinged to the car-roof in of Ohicago,lllinoi s,haveinvented certain new .any suitable manner, although I prefer the and useful Improvements in Ventilators for construction shown, in which the coaming is 5 Refrigerator-Cars, of which the following is a both hinged or sliding.

This invention relates to ventilators for reposed of a plurality of sections 22, each comfrigerator-cars, and has for its object to proprising side portions 23 and a top or back vide a device of this character which will be portion 24:, the several sections havinga com- IO efficientin use and which when not in use may mon pivotal axis and being so constructedas be easily stored away in a compact manner to be'capable of sliding over each other when for use. I it is desired to fold the hood, as shown in Fig. To these ends my invention consists in cer- 2. In conjunction with these hood-sections tain novel features which will be hereinafter I employ a'bas'e-plate 25, to which said secr 5 described and then specifically pointed out tions'are pivotally connected and which is itin the claims. self pivotally connected at 26 to the coaming.

I prefer to protect the sealedlocking-pin or the like. mouth of the hood by a suitable screen 30,

I prefer to connect the coaming 12 to the which is attached to the outermost or uppercar-roof in the manner set forth in an applimost section 22 and which serves to prevent cation filed by me jointly with Francis J. Mcthe entrance into the car of cinders orthe like.

45 AsseyJuly6, 1897, Serial No. 543,637-2'. 'e.,by In order to render the hood automatic or making said coaming slidable along the roof self-opening, Iapply theretoaspring3l,which and providing ways or tracks 18,which are protends to throw the hood-sections upward and vided for a portion of the length of their veroutward. This spring is in the preferred tical portions with slots 19, with which pins construction shown coiled around and cen- I03 50 or rollers 20 on the coaming engage to prevent trally secured to a transverse rod or shaft 32, displacement or removal of said coaming;-but which is itself secured to the base-plate 25.

The ends of the spring 31 pass loosely through all of the sections of which they form the pivot and are extended upward and secured to the outermost section 22. This spring serves to raise the hood into the position shown in Fig. 1 and to hold it in said position, the other sections following the section to which the spring is attached by reason of the intermediate connecting devices described. Then the ventilator is not in use, it may be folded back in the manner shown in Fig. 2 and the cover closed and locked to prevent access to the interior of the car. When the car is to be used as a refrigerator and it becomes necessary to place ice in the tanks, the entire eoaming, hood, and cover may be either slid back out of the way along the tracks 18 or they may be swung back and out of the way by turning them on the pins 20 as pivots.

It is obvious that various modifications in the details of construction may be made without departing from the principle of my invention. For instance, the hood sections may be differently shaped in transverse sectional form. I preferthe construction shown, however, since it alfords the greatest capacity of the ventilator. Moreover,the construction and location of the spring may obviously be varied as well as the particular construction of the devices connecting the sections. I have shown in Fig. 4 a modification in'whieh the cover is made in two parts 15 and 15 hinged, respeetively,to the front and rear edges of the eoaming and provided with a hook and eye for locking their meeting edges.

- With this construction when the front plate or section 15 of the cover is folded down in the operation of closing the cover it will carry with it the folding hood, which is thus closed by the act of closing the cover. I also prefer in this construction to omit the chain 27, as shown in the drawings.

I claim- 1. In a ventilator for refrigerator-cz'trs, the combination, with a car-roofhaving an icehole, of a hood composed of overlapping pivoted sections and a spring forliftingand holding said sectional hood in operative position, substantially as set forth.

2. In a ventilator for refrigerator-cars, the combination, with a car-roof having an icehole, of a eoaming movable relatively to said ice-hole, a hood composed of overlapping sections pivoted to the eoaming, and a solid cover hinged to the eoaming and adapted to cover the ice-hole and hood when the latter is folded, substantially as set forth.

3. In a ventilator for refrigerator-cars, the combination, with a car-roof having an icehole, of a eoaming movable relatively to said ice-hole, a hood composed of overlapping sections pivoted to said eoaming and provided with a spring for lifting and holding said sectional hood in operative position, and a solid cover hinged to the eoaming and adapted to cover the ice-hole and hood when this latter is folded, substantially as set forth.

4. In a ventilator for refrigerator-cars, the combination, with a car-roof having an icehole, of a hood composed of overlapping sections having a common pivotal axis, the outermost of said sections being provided with a screen covering the mouth of the hood, substantially as set forth.

5. In a ventilator for refrigerator-ears, the combination, with a car-roof having an icehole, of a eoaming having a hinged imperforate cover, and a hood composed of pivoted overlapping sections and a base-plate pivoted to the eoaming and connected to the cover, substantially as set forth.

6. In a ventilator for refrigerator-cars, the combination, with a car-roof having an icehole, of a eoaming for said hole, a hood composed of pivoted overlapping sections, and

an imperforate cover composed of two sec-- tions hinged to opposite edges of the eoaming, substantially as set forth.
